You could build an email list using something as simple as Google Forms, and technically, it works.
But here’s the thing: if you want an email list that grows fast, converts well, and actually drives revenue, you’ll need a tool that’s purpose-built for it.
In this guide, I won’t be discussing makeshift workarounds; I’ll present some dedicated email list building tools that are packed with the essentials: smart targeting, popups that convert, deep integrations, and automation that does the hard work while you sleep.

Email list building tools: comparison criteria
Not every email list-building tool works the same way, and not every marketer needs the same thing. To help you choose the right one, here’s how I evaluated each tool in this guide:
Selecting service type
Service type is the first thing to check since it largely affects how you use it.
Some tools in this list, like OptinMonster, OptiMonk, and Sleeknote, are dedicated popups and form builders. They help you capture email addresses directly from your website using smart triggers, beautiful forms, and personalization. That’s it.
The given tools don’t send emails, manage your campaigns, or do list segmentation. Instead, they plug into your existing email marketing tool, so if you already use something like Mailchimp or Klaviyo, these can be powerful add-ons that boost your list growth.
Conversely, tools like Mailchimp, Klaviyo, and HubSpot are like all-in-one email marketing platforms. They give you the full toolkit: popups, email sending, automation, segmentation, SMS, and CRM under one roof. These are great if you want to avoid juggling multiple tools and just want one place to manage your audience from signup to sale.
So while comparing, I grouped the tools into two categories:
- Do they only capture leads (standalone)?
- Or do they capture and nurture those leads through full-service?
This helped me evaluate each tool based on what it’s actually meant to do.
Pricing
Pricing is important to determine what you get from the tool at each tier. It also affects the service cost when your business scales, increasing the demand for list building. Also, I focused on whether the “free plans” are genuinely useful.
Particularly, I looked at the following:
- Is there a free plan? And what does it include? (Many free plans cut off key features like A/B testing or integrations.)
- How is the pricing calculated? Some charge based on the number of contacts (like Mailchimp and Klaviyo), while others use pageviews (OptiMonk) or email sends.
What features are locked behind higher tiers? For example, things like exit-intent popups or lead verification are sometimes available only on mid- or top-tier plans. - What’s the jump like as you scale? Some tools double in price when your list crosses certain thresholds.
For instance, Mailchimp and Klaviyo offer free plans that are great for getting started. You can collect emails, send basic campaigns, and try out automation. But as your list grows, so does your bill.
Others like OptinMonster or Sleeknote don’t offer a free plan at all. Instead, they give you a short trial or a money-back window, which is fine if you want to test the waters.
Email list-building features
When checking the tool’s core list-building capabilities, here’s what I paid close attention to:
- Form variety: popups, slide-ins, inline forms, sticky bars, full-screen mats, and multi-step formats.
- Trigger and display controls: scroll depth, time on page, exit intent, cart value — anything that makes targeting smarter.
- Personalization options: dynamic content, behaviour-based offers, or audience-specific messaging were a big plus.
- Custom fields support: collecting more than just a name and email stood out for building richer segments.
- Lead magnet delivery: instant access to downloads or coupons post-signup made the user experience smoother.
- A/B testing: easy-to-run tests on headlines, designs, timing, and how the results are presented.
AI and integrations
AI is helpful in email list building, not for writing your emails (though it can help there, too). But, in this context, it can make your forms smarter, segments sharper, and data cleaner from day one.
Here’s what I looked for:
- AI-enhanced form building: AI suggestions for copy, design layout, and targeting to help you launch high-converting forms faster.
- Predictive segmentation: machine learning to group contacts or flag unengaged users early, which is great for keeping your list lean and effective.
- Real-time lead verification: filter fake emails, bots, or mistyped addresses before they ever hit your list.
The integrations relate to how easily each tool connects with email marketing platforms, CRMs, and e-commerce stores. A good integration means new contacts are automatically added to the right segment, tagged properly, and ready to receive relevant emails.
Also, bonus points went for tools that sync behavioural data, product views, or even quiz responses to personalize sign-up forms in real time.
User experience
While testing each platform, I considered how smooth the experience was, especially when setting up forms, customizing campaigns, and managing contacts day to day.
Here’s what I examined:
- Ease of setup: tools that made it simple to go from idea to live pop-up in minutes. Drag-and-drop editors, quick-start templates, and guided wizards all helped.
- Navigation and form building: how easily you can add fields, change styling, preview mobile views, and set targeting rules without clicking through five different menus.
- Onboarding & learning curve: tooltips, checklists, or onboarding flows without trial and error.
- Help resources: should always include tutorials, help docs, video walkthroughs, and live chat support. These are especially important for list building when you hit a blocker and need a fast answer on how to set triggers or connect integrations.
- Form previews & testing: test exactly how your form would look and behave across devices before publishing it.
Legal compliance
Legal compliance isn’t optional, especially when you’re collecting personal data like emails.
I checked if each tool supports:
- GDPR-ready features include the ability to add consent checkboxes, privacy policy links, and clear consent language to your forms.
- Double opt-in support: helps confirm subscriber intent, reduces fake signups, and improves deliverability.
- Cookie and tracking controls: options to respect user tracking preferences and integrate with cookie banners.
- Region-based controls: ability to hide or customize popups for visitors from GDPR or CCPA regions.
- Responsible data handling: clear unsubscribe options, data privacy settings, and contact storage policies.
Customer experience
I started by reading through dozens of reviews on platforms like G2, Capterra, and even Reddit. These gave me an unfiltered insight into what users love, what frustrates them, and what they wish the tool did better. I paid special attention to recurring themes, whether people praised the UI, ranted about bugs, or appreciated how quickly support responded.
Next, I tested how accessible the support is. Some tools offer live chat on nearly every page, while others hide support behind paywalls or limit it to email-only help. I noted whether basic plan users could still reach someone when needed, and how clear the escalation path was.
I also spent time exploring each platform’s help centre and documentation. So I looked at how easy it was to find setup tutorials, walk-through videos, form guides, and answers to common issues like trigger settings or integration errors.
Additionally, I considered brand credibility and real-world results. If a tool had been used by known brands or they shared measurable success stories (like massive list growth or conversion lifts), that gave me confidence it wasn’t just marketing fluff.
Continuing with the discussion, let’s now explore the tools I’ve lined up for you in greater detail.
OptinMonster
